   12  * Note: this Device Tree assumes that the bootloader has remapped the
   13  * internal registers to 0xf1000000 (instead of the default
   14  * 0xd0000000). The 0xf1000000 is the default used by the recent,
   15  * DT-capable, U-Boot bootloaders provided by Marvell. Some earlier
   16  * boards were delivered with an older version of the bootloader that
   17  * left internal registers mapped at 0xd0000000. If you are in this
   18  * situation, you should either update your bootloader (preferred
   19  * solution) or the below Device Tree should be adjusted.
